My b/f gets them once in a while. They seem to be random.

Do you eat more of something now that you didn't used to, before LCing? Maybe nitrates in meat, or artificial sweeteners? Dairy?

Just a few thoughts.

(My poor b/f... the only time he's had one since we've lived together, he woke up with one and didn't know either of our names. He was sick and out-of-commission for days.)
